NASA released two satellite photos taken on September 7, 1986 and August 1, 2019 showing the difference in Okjökull glacier's top view in Iceland. As Iceland's Prime Minister said: "The ice is leaving." Okjökull is the first Icelandic glacier to officially lose its status as a glacier and was declared dead in 2014. /VCG Photo

The disappearance of the first glacier serves as a warning that climate change threatens 400 other glaciers on the subarctic island. In the west of Iceland, a bronze plaque will be unveiled marking Okjokill (translates to "Ok Glacier") to draw attention to what is being lost as Earth's glaciers die. Local researchers and their peers at Rice University in the United States will join the Okjokill project. /VCG Photo
